should help you out i is the starting column, j is the starting row, and you're checking 4 adjacent rows/columns. If you didn't subtract 3 from the width/height respectively you would overflow into non-existent rows/columns.
Edit: In fact the left diagonal code is bugged and will overflow the board. Should be like this:
code :
//checks left diagonal win
        if(board[i][j] != 0 && board[i][j]==board[i+1][j-1] && board[i][j]==board[i+2][j-2] && board[i][j]==board[i+3][j-3])

Making a Regex object that matches a Javascript string. Explain method

With these it helps In JavaScript, strings are surrounded by " (or ', which this regex doesn't support) and \ is used to escape characters that would otherwise have a different meaning.
Now, [^\\\\\\\"] is a character class for characters that aren't \ or ". However because we're using a string literal to define the regular expression the " needs escaping, and because \ has a special meaning within both strings and regular expressions we need to escape them too.
code :
\"        starting characters
\\"       escape `\` for regex
\\\"      escape `"` for regex
\\\\\\"   escape `\` for string
\\\\\\\"  escape `"` for string
new RegExp("\"(?:\\.|[^\\\\\\\"])*\"", "g");
new RegExp('"(?:\\.|[^\\\\\\"])*"', 'g');

Hope this helps here you are not creating a new object when you are assigning the value ver[i] = touchpos
so all your our referances ver[0], ver[1] ... etc else are same objects touchpos.
code :
camera.unproject(touchpos.set(Gdx.input.getX(), Gdx.input.getY(),0));

I think the issue was by ths following , You will want to set NONE to '.', not a space. Then, you could make such a print function for the board:
code :
def printBoard (b):
    print('  '.join(map(lambda x: str(x + 1), range(BOARD_COLUMNS))))
    for y in range(BOARD_ROWS):
        print('  '.join(b[x][y] for x in range(BOARD_COLUMNS)))
>>> x = _new_game_board()
>>> printBoard(x)
1  2  3  4  5  6  7
.  .  .  .  .  .  .
.  .  .  .  .  .  .
.  .  .  .  .  .  .
.  .  .  .  .  .  .
.  .  .  .  .  .  .
.  .  .  .  .  .  .
>>> x[1][-1] = RED
>>> x[1][-2] = RED
>>> x[1][-3] = YELLOW
>>> x[2][-1] = RED
>>> x[2][-2] = YELLOW
>>> x[2][-3] = RED
>>> x[2][-4] = YELLOW
>>> printBoard(x)
1  2  3  4  5  6  7
.  .  .  .  .  .  .
.  .  .  .  .  .  .
.  .  Y  .  .  .  .
.  Y  R  .  .  .  .
.  R  Y  .  .  .  .

Java making Connect Four game panel

I wish this help you I think you want to and a new JPanel instead of just making it = to the empty panel. What's happening is that you are trying to add one component to a parent containter multiple times, which won't work. A component can only be added once. So you the result you're getting, is the only the gridPanel slot being added an emptyPanel
code :
public static void fillGrid() {
    for(int j = 0; j < 6; j++) {
      for (int k = 0; k < 7; k++) {
        gridArray[j][k] = new JPanel();
        gridArray[j][k].add(new Label(emptybox));

private JPanel greateOnePanel(){
    JPanel panel = new JPanel();
    ImageIcon icon = new IMageIcon("emptybox.jpg"):
    JLabel label = new JLabale(icon);

    return panel;
public static void fillGrid() {
    for(int j = 0; j < 6; j++) {
      for (int k = 0; k < 7; k++) {

With these it helps The simplest way (I can think of) is having a separate GUI class which extends Jframe and implements Action Listeners. This way you could have a simple text box in a frame with a couple of buttons.
